How it Works


Simply put, Syntra-Shield's active ingredient (a patented yeast-derived gluco polysaccharide) activates a large population of the body’s own immune cells to enhance natural defenses against foreign challenges. Once swallowed, It is taken up into the body through the Peyer’s Patches, specialized regions in the small intestines. There are immune cells called macrophages that engulf the active ingredient in Syntra-Shield and degrade it into smaller fragments that bind to neutrophils, the most abundant immune cell in the body. Primed with this unique ingredient, neutrophils more effectively circulate throughout the body and kill foreign challenges.

Natural Products Insider

"Subjects taking the active ingredient in Syntra-Shield reported a 42% increase in vigor and 38% reduction in fatigue, and significantly fewer subjects on active treatment had any type of upper respiratory infection symptoms."



"In a double-blind, placebo-controlled study with 40 subjects 18-65 years old, the active ingredient in Syntra-Shield (a patented yeast-derived gluco polysaccharide) reduced the incidence of fever & elimated the need to miss work or school due to cold-like symptoms." Results were presented at Experimental Biology 2008.



"The active ingredient in Syntra-Shield activates a natural immune mechanism to increase the ability of macrophages to phagocytose or engulf and destroy foreign challenges"


Nutraceutical World

"Syntra-Shield's active ingredient primes key immune cells, including macrophages and neutrophils (types of white blood cells), to quickly identify and kill foreign challenges."

Before Ordering Read This!

We encourage you to do your due dilligence, but other products will make claims based on anecdotal evidence and third party research regarding some of their ingredients. They market their products with hype, prices and free offers. When reading their websites watch for terms like "has been proven to" and "our proudct has shown to." Ask yourself where is the proof and where is the study? We spent hundreds of thousands of dollars on a third party, gold standard clinical trial and have posted the factual results on this website.
